"Hopefully, the MRI is not as bad as I think it might be," said Mike Shanahan

Running back Clinton Portis does not expect to play against the Packers on Sunday because of the groin injury he suffered in Philadelphia.

"I don't think the team would even let me attempt to go and try to play on Sunday," he said Tuesday during an appearance on The Mike Wise Show. "But who knows?"

Portis expects results back soon on an MRI on the area "up above the private spot," admitting that he heard a "pop" in his groin during the Redskins' 17-12 win over the Eagles.

Just a week after being questioned for sliding to avoid contact at the end of a 27-yard run, Portis had been hard at work on Sunday, rushing for 55 hard-fought yards and catching two passes for 26 before he could go no further.

"Any time he goes out like he did and puts street clothes on during a game, I'm concerned," coach Mike Shanahan said. "I know him. I've been around him too long. He's [the type] to play hurt.

"Hopefully, the MRI is not as bad as I think it might be," Shanahan said. "Just have to keep our fingers crossed."

The question is, apparently, exactly how long Portis will be on the sidelines. Young back Ryan Torain gained 70 yards and scored once on Sunday, helping spark the team to a much-needed victory, but he's fresh off the practice squad and it's unclear how effective he can be largely on his own against Green Bay -- or beyond.

"I’m going to take time to make sure I’m healed," Portis said. "Being in the condition that I'm in, I think my recovery will be fast."
